Independent publication
Silicosis, engineered stone and the litigation around them, documented from primary sources.
Silicosis Lawsuit is an independent, evidence-led reference on silicosis: the disease, the occupational silica exposure that causes it, the engineered-stone outbreak, the lawsuits and verdicts that have followed, and the regulation and resources that affect workers. It is written for workers and families, journalists, researchers and lawyers, and every material claim is tied to a cited source.
This site is not a law firm and does not take claims. If you need a lawyer, start with finding an attorney.

Why engineered stone is the story
Engineered stone, the quartz countertop material, is typically more than 90% crystalline silica. Cutting and polishing it without effective dust control has produced an outbreak of accelerated silicosis among fabrication workers, concentrated in California and falling largely on young Latino immigrant men. It is now at the centre of product-liability litigation against manufacturers, of Cal/OSHA rulemaking, and of a debate over banning the material.

The record, in numbers
Every figure on this site comes from a record you can download: the verdict tracker, litigation tracker, defendant index, regulation register, California timeline, research timeline and worker resource directory, all on the open data page as CSV and JSON. Each record carries its sources and a verification label.
California
The outbreak, the rules and the trials are concentrated in one state. The California overview puts the numbers, the regulatory response and the litigation on one page; the timeline lists what happened when.
